Prestressed concrete laminated slab bottom plate and preparation method
The invention discloses a prestressed concrete laminated slab bottom plate and a preparation method, and belongs to the technical field of house building engineering. The transverse bars are arranged between the lower-layer longitudinal bars and the upper-layer longitudinal bars to form a three-layer structure, or the longitudinal bars are arranged between the lower-layer transverse bars and the upper-layer transverse bars to form a three-layer structure. And the longitudinal bars are prestressed reinforcements. The two-way prestressed concrete laminated slab bottom plate is prepared when the transverse bars are also prestressed steel bars, and the one-way prestressed concrete laminated slab bottom plate is prepared when the transverse bars are common steel bars or steel wire meshes. When the three-layer structure is arranged, the center of the prestress resultant force and the center of the concrete thickness of the prestress concrete bottom plate are located on the same horizontal plane as much as possible, and the warping phenomenon caused by the fact that the center of the prestress resultant force of the prestress steel bars is eccentric relative to the center of the concrete thickness of the prestress concrete bottom plate can be effectively prevented. The prestressed concrete laminated slab bottom plate is good in quality, high in rigidity and excellent in crack resistance, and the construction quality of the concrete laminated slab is guaranteed.
一种预应力混凝土叠合板底板及制备方法，属于房屋建筑工程技术领域。本发明在下层纵筋和上层纵筋之间布置横筋形成三层结构，或者在下层横筋和上层横筋之间布置纵筋形成三层结构。纵筋均采用预应力钢筋。横筋也采用预应力钢筋时制备的是双向预应力混凝土叠合板底板，横筋采用普通钢筋或钢丝网片时，制备的是单向预应力混凝土叠合板底板。三层结构在布置时要尽量使其预应力合力中心与预应力混凝土底板混凝土厚度的中心在同一水平面上，可有效防止因预应力钢筋的预应力合力中心相对于预应力混凝土底板混凝土厚度的中心偏心，从而产生翘曲现象。预应力混凝土叠合板底板质量好、刚度强、抗裂性能优异，保证了混凝土叠合板的建造质量。
